Thanks Doug, I agree.
Thanks Ryan! I've seen several done like this and just knew that I had to do it when I got to this point. I think it will be worth the effort.
Thanks Mike!
Thanks Mike!

I've got a little more done:

I really need to move that fuel line out of my way. After seeing it in these pictures, I'm a bit surprised I haven't put it back down by the frame rails yet. :lol:

Re: Knomadd '71 SWB C-10
 

Awesome job on the firewall Duane, I really like the shaved wire gutter!

Re: Knomadd '71 SWB C-10
 

Nice clean look, Duane. Looks like you've almost got it whipped.

Re: Knomadd '71 SWB C-10
 

Thanks Keith!
Thanks Vic! It's taking me longer than I'd like, but it's coming along.

Well, I didn't take final pics of the passenger side, but here is one of the drivers side and another of the passenger side with the A/C fittings mocked up.

I've started sanding down the rest of the firewall and will be filling in some unnecessary extra holes, relocating some others for some wiring to hide a little better, and start body work. Hopefully I'll get it ready for paint around Thanksgiving.

Oh, and my wire harness should be here tomorrow!!! :metal:

Re: Knomadd '71 SWB C-10
 

Damn. Good work. Looks great.

Re: Knomadd '71 SWB C-10
 

Excellent work on the channel Duane!

Re: Knomadd '71 SWB C-10
 

Thanks guys!

I went out to the garage last night to keep plugging holes, got two done, but noticed it was welding really strange. It took me until the 2nd hole was filled to check my gas level... it was empty, again! Now I know I don't weld often, but that tank sure seemed to go empty rather quickly. :lol:

So, no more progress with the welds, but I did take a picture of the passenger side finished.

And...

MY HARNESS CAME IN!!!
http://67-72chevytrucks.com/gallery/...pswpgfzc4n.jpg

Now I just need to finish the firewall, get it off to paint and I can start cutting it down and building my own stand alone harness! :metal:

Re: Knomadd '71 SWB C-10
 

Sucks when you run out of gas, it always happens to me on the weekend too it seems.....
Nice harness! where'd you end up buying it?

Re: Knomadd '71 SWB C-10
 

Your firewall is looking awesome!

Re: Knomadd '71 SWB C-10
 

That happened last time! Luckily, it wasn't the weekend this time, but still when the welding supply place was closed. Got my refill today at lunch though, so welding continues tonight! As for the harness, it's a factory piece. Since mine was damaged in shipping, the seller sourced a brand new one. Apparently, the factory harness that came with my engine wasn't available anymore, so it had to be built. We had to wait for GM to commission this harness for the 2017 vans in order to get one. I'm now at "ground zero" where I should have been when I received my engine back in July.

Thanks Ryan!

Re: Knomadd '71 SWB C-10
 

More progress... the metal work is almost complete!

Started with these holes
http://67-72chevytrucks.com/gallery/...pskggbxbem.jpg

made a plug
http://67-72chevytrucks.com/gallery/...psehemb3nt.jpg

two holes down, square plug set in place
http://67-72chevytrucks.com/gallery/...psoovxvkuf.jpg

end result (keeping rear body harness hole since I wired the truck already)

Clutch hole before
http://67-72chevytrucks.com/gallery/...pshbrd9ss2.jpg

and after
http://67-72chevytrucks.com/gallery/...psdn0g3erb.jpg

started stripping the undercoating/bedliner crap and surface rust that was hiding under it
http://67-72chevytrucks.com/gallery/...psh1pz75wv.jpg

Final product, with some rust converter on the drivers side. Just to keep it at bay. Once I'm ready to cut out and replace the fuse block butcher job, I'll sand it all off again and start filler work.

Re: Knomadd '71 SWB C-10
 

Wow that looks really good man. Great job

Re: Knomadd '71 SWB C-10
 

That looks really nice. Great work!

Re: Knomadd '71 SWB C-10
 

Nice work, Duane. I like the a/c line hole layout better than mine which is all inline. The rain gutter turned out slick.

Re: Knomadd '71 SWB C-10
 

Thanks guys!

The last piece of the firewall... The butchered fuse block hole... old overlayed onto new.
http://67-72chevytrucks.com/gallery/...psoyodqxij.jpg

And the finished product, finally!
http://67-72chevytrucks.com/gallery/...pspvxrfa1c.jpg

Oh, and my e-level reprogrammed and resurfaced accuair parts came in yesterday. These were my old switchspeed parts sent back in to accuair for the upgrade.

Re: Knomadd '71 SWB C-10
 

Very nice work on the firewall...well done!

Re: Knomadd '71 SWB C-10
 

Looks great! Killer progress.

Re: Knomadd '71 SWB C-10
 

Nice work Duane. Hope those pinouts help you out on that harness too!

Re: Knomadd '71 SWB C-10
 

Apparently I've forgotten to update this thread for a little while. Time to remedy that...

Metal work finished, rolled it outside to blow it all of and give it a good grease and wax remover clean up.
http://67-72chevytrucks.com/gallery/...psx1sdeeoa.jpg

http://67-72chevytrucks.com/gallery/...psmy4h7xeh.jpg

I then started with some filler...
http://67-72chevytrucks.com/gallery/...pszxtcgscd.jpg
First coat done and sanded...
http://67-72chevytrucks.com/gallery/...psxxkbhjz5.jpg

After a little more filler, it was time to do a polyester filler (final filler).
http://67-72chevytrucks.com/gallery/...pso0mnootk.jpg

I've almost got it finished, but still some sanding and a couple touch up spots to hit again... more pictures later.

Re: Knomadd '71 SWB C-10
 

Got a bit more done last night. Hopefully this is the last time I'm putting on more filler...

Re: Knomadd '71 SWB C-10
 

awesome work!

what are you using to sand down your firewall?

Re: Knomadd '71 SWB C-10
 

Looks great Duane!

Re: Knomadd '71 SWB C-10
 

Keep plugging away, your almost there..it looks great man!

Re: Knomadd '71 SWB C-10
 

Smooooooth

Re: Knomadd '71 SWB C-10
 

I start with 36 grit, move to 80, then 220. Once I apply the polyester filler I use 220 grit, unless it's too thick then I'll start with 80 to get it close then finish it with 220. I do all of it with hard blocks. I have used an electric orbital to get excess filler knocked down to a manageable shape quickly, but it's pretty risky if you aren't careful with it.

Thanks guys! I'm excited to say that I finished the filler work on the firewall. It's going to be delivered to a friends house this evening to have some color put on it. Hopefully I did the work to his satisfaction (not just mine) and he'll get some primer and color on it this weekend.
Here's the final shot before it gets covered up.
